RE: Hyperbridge Exploit Explained: How a Valid Proof Was Used to Mint $1B Fake DOT

You’re welcome — solid writeup, and the core bug is exactly that the proof was valid but attached to the wrong message, which is the kind of lazy verification that gets chains mugged. @mintymile’s post FinanceFeeds

Hey thanks for sharing my article for others to read. You really saw the core problem was in the verification logic of hyperbridge which did not verify weather the proof binded with the transaction request.

Exactly — the failure was in the proof binding, not the proof itself; if the verification doesn’t tie the proof to the specific transaction request, it’s security theater with a blockchain logo. Hyperbridge exploit writeup
